How can you use eye-tracking to improve your data visualization storytelling?

Data visualization storytelling is the art of communicating insights, patterns, and narratives through visual elements such as charts, graphs, maps, and dashboards. It can help you engage your audience, persuade them to take action, or inform them about complex topics. But how do you know if your data visualization storytelling is effective? How do you measure the impact of your design choices, such as colors, shapes, layouts, and annotations? One way to answer these questions is to use eye-tracking.

Key takeaways from this article

Optimize layout placement:

Eye-tracking reveals how viewers' attention flows, guiding you to position key elements where they'll have the most impact. This ensures your story is told effectively and insights don't go unnoticed.
Define your objective:

Before visualizing data, clearly define what you're analyzing. A focused objective ensures that your story is clear and compelling from the start, without relying on visual cues alone.

1 What is eye-tracking?

Eye-tracking is a method of measuring where people look, how long they look, and how they move their eyes when they view a visual stimulus, such as a data visualization. Eye-tracking can be done with specialized devices, such as glasses or cameras, that record the eye movements and gaze patterns of the participants. Eye-tracking can also be done with software tools, such as web-based platforms or plugins, that simulate the eye movements and gaze patterns of the users based on mouse movements, clicks, and scrolls.

2 Why use eye-tracking?

Eye-tracking can provide you with objective and quantitative feedback to improve your data visualization storytelling. It can help you answer questions such as what elements of your data visualization draw the most and least attention, how your audience scan and navigate it, how they interpret and understand it, how they recall it, and how they feel and react to it. By analyzing the eye-tracking data, you can identify the strengths and weaknesses of your storytelling and make adjustments accordingly.

3 How to use eye-tracking?

To use eye-tracking to improve your data visualization storytelling, you should first define your research question and hypothesis. Then, you need to choose the eye-tracking method and tool that best suits your needs. After that, you should design the eye-tracking experiment, including the number of participants, tasks, and metrics. Once the experiment is ready, you should guide and collect the eye-tracking data. Finally, you need to analyze and interpret the data to draw insights and conclusions from it.

4 What are some eye-tracking metrics?

Eye-tracking metrics are numerical or graphical indicators that describe the eye movements and gaze patterns of the participants. Fixations indicate the focus of attention and the processing of information, while saccades indicate the exploration and search of information. Heatmaps show the areas of interest and the attention hierarchy of a data visualization, while gaze plots show the scan path and navigation strategy. Areas of Interest (AOIs) are predefined regions or segments of a visual stimulus that are relevant for the research question or hypothesis, allowing comparison and analysis of eye-tracking metrics across different parts of a data visualization.

5 What are some eye-tracking best practices?

Eye-tracking can be a powerful and useful method for improving data visualization storytelling, but it also has some limitations and challenges. To ensure the best results, you should align your eye-tracking method and tool with your research question and hypothesis. Additionally, it's important to test your eye-tracking experiment before conducting it with participants. You should also provide clear and consistent instructions and feedback to participants, and make sure the validity and reliability of your eye-tracking data is checked. Lastly, you should interpret your eye-tracking data with caution and context, without making assumptions or generalizations based solely on the data.
